bear351c 10,260 Posted September 24, 2021 I would say, it's probably for the old style "wide" bearings. Dont think many people use them anymore, the side loads when cornering wore them out prematurely, I believe. Not 100% sure, The 9" s that I have used, shortened, fitted all had the thinner bearings, and standard axle plates. 1 gerg reacted to this Share this post Link to post Share on other sites
Jon Kirkwood 0 Posted September 30, 2021 It is a drum brake rear. It has the normal narrow bearing the spacers appear to do nothing does not change diff length or brake offset. Share this post Link to post Share on other sites
bear351c 10,260 Posted October 2, 2021 Oh ok, not sure then. Maybe spacer plates as you said. XY is about an inch or so shorter than an XA, (I think?) Share this post Link to post Share on other sites
